Bon Iver took the stage at Cork Opera House in Ireland last night, where they delivered a set that drew heavily from their most recent album 22, A Million. Near the end of the night, Justin Vernon was joined by Aaron and Bryce Dessner of the National, who played with him on “33 ‘GOD’” and “The Wolves (Act I and II).” Fionn Regan also made an appearance, to help perform his song “Abacus” as well as the Bon Iver track “00000 Million.” Watch that all go down below. The National recently released their seventh studio album Sleep Well Beast.
